Furthermore, we found that IDO-dependent Trp metabolism by SMCs regulates VCAM-1 expression, and that 1-MT-induced acceleration of atherosclerosis and vascular inflammation can be reversed by exogenous administration of the Trp metabolite 3-hydroxyanthranilic acid (3-HAA).
A crucial pathology change of atherosclerosis is the migration of activated VSMCs to the intima where they interact with leukocytes by expressing adhesion molecules, including intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1).
Finally, transgenic mice containing a kinase-dead mutation in FAK specifically in the endothelial cells show reduced RSK activity, decreased VCAM-1 expression and reduced macrophage accumulation in regions of early atherosclerosis.
VCAM-1 has therefore been identified as a potential anti-inflammatory therapeutic target, the hypothesis being that reduced expression of VCAM-1 will slow the development of atherosclerosis.
Thus, we have shown that rosiglitazone appears to have direct anti-atherosclerotic effects in an animal model of diabetes-associated atherosclerosis which are at least partly due to effects on VCAM-1, ICAM-1, MCP-1 and P-selectin expression which leads to decreased leukocyte adhesion and macrophage infiltration.
Testosterone attenuates expression of vascular cell adhesion molecule-1 by conversion to estradiol by aromatase in endothelial cells: implications in atherosclerosis.
Vehicle-treated ApoE(-/-) mice exhibited significant increases in aortic inflammation and atherosclerosis as well as enhanced expression of HMGB1, RAGE, VCAM-1, and MCP-1 in aortic tissues as compared to the wild-type mice.
Our study first indicated that atorvastatin might exert its anti-inflammatory effects in atherosclerosis by regulating the expressions of miR-126 and VCAM-1 in vivo.
Among our most noteworthy findings are that DHL exerts an inhibitory effect against the increased expression of VCAM-1 and E-selectin induced by exposure to oxidized low-density lipoprotein (ox-LDL), which has been linked to the development and progression of atherosclerosis.
Mechanism study showed that DHPV prevents THP-1 monocyte-endothelial cell adhesion by downregulating TNF-α-stimulated expressions of the two biomarkers of atherosclerosis such as vascular cell adhesion molecule-1 and monocyte chemotactic protein-1, activation of nuclear factor kappa B transcription and phosphorylation of I kappa-B kinase and IκBα.
Our data define a major proatherogenic role for endothelial NOD1 in early leukocyte recruitment to the athero-prone vasculature, thus introducing NOD1 as an innovative therapeutic target and potential prognostic molecule.-González-Ramos, S., Paz-García, M., Rius, C., del Monte-Monge, A., Rodríguez, C., Fernández-García, V., Andrés, V., Martínez-González, J., Lasunción, M. A., Martín-Sanz, P., Soehnlein, O., Boscá, L. Endothelial NOD1 directs myeloid cell recruitment in atherosclerosis through VCAM-1.
miR-1185 modulated the expression of VCAM-1 and E-selectin to promote arterial stiffening, suggesting that miR-1185 plays a crucial role in the development of atherosclerosis and may serve as a novel therapeutic target for atherosclerosis.
Fine-mapping of the Chr3 locus revealed two overlapping, yet independent subloci for female atherosclerosis susceptibility: when transmitted by grandfathers to granddaughters, the B6 risk allele increased atherosclerosis and downregulated the expression of the secreted phospholipase Pla2g12a (2.6 and 2.2 fold, respectively); when inherited by grandmothers, the B6 risk allele induced vascular cell adhesion molecule 1 (Vcam1).
Vascular cell adhesion molecule-1 (VCAM-1) is expressed in early stages of atherosclerosis; however, the mechanisms of its upregulation are not fully understood.
Our results indicate that QA inhibits the TNF-α-stimulated induction of VCAM-1 in VSMC by inhibiting the MAP kinase and NF-κB signaling pathways and the adhesion capacity of VSMC, which may explain the ability of QA to inhibit vascular inflammation such as atherosclerosis.
Using en face immunofluorescence, we further demonstrate selective PV-MPIO accumulation at atherosclerosis-susceptible sites, with minimal binding to atherosclerosis-spared regions.
K(1-5) reduced atherosclerosis and neointima formation in mice, possibly through inhibition of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 expression in endothelial cells.
Studies in animals have shown that resistance to atherosclerosis in spite of hypercholesterolemia is affected by factors such as high-density lipoprotein (HDL) phospholipids that enhance reverse cholesterol transport, non-responsiveness to induction or lack of monocyte chemotactic protein-1 (MCP-1), C-C chemokine receptor 2 (CCR2), macrophage colony stimulating factor (MCSF), or vascular cell adhesion molecule-1 (VCAM-1).
Indeed, in a mouse model of atherosclerosis, (99m)Tc-cAbVCAM1-5 specifically bound to VCAM-1-positive lesions, thereby allowing their identification on SPECT images.
Circulating markers of atherosclerosis including vascular cell adhesion molecule-1, E-selectin, and P-selectin decreased after both interventions (all P < 0.05).
Intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) may be important contributors to the development and progression of atherosclerosis.
